Sean,
The air lock is most likely hanging up slightly on the hook lock on the door. Check to make sure that hook isn't cracked. The ideal situation is that the lock will release slowly as you come to a stop, but the extra pressure will cause it to drop suddenly, making the snapping noise.
The solution is to slightly losen the air lock roller assembly screws and adjust it by small amounts until it stops hanging up, but to not move it too much or you'll lose the locking effect and introduce a lot of air noise. When I did this, I first marked the starting point, then made a slight adjustment, drove far enough to cause the lock to activate, then stopped to hear the effect of my change. It took several trys before I got it to an acceptabe spot. It will change a little over time, so you'll probably need to do it again in a few years.
Good luck.
